Contingency Network


Network Infrastructure as key element

Highly reliable / Security – Redundant links / separated routes / secure channels

Contingency Concept (degraded modes)

Transferring Voice, Data, Video via same network– Bridging legacy protocols

Address high bandwidth demand for video – optimize compression– reduce data be selecting other camera technology

Provide high level of safety but keep your infrastructure costs low !


Do not only a replacement the tower view – enhance it !

How to get acceptance from the ATCOs and approval by regulator ?


Benefits of Thermal Infrared Cameras

Better Ground / Sky Contrast allows detection of object even with

lower resolution

Enhanced Visibility in Heavy Rain, Snow/Sandstorm, Fog etc

No sunlight reflection / Equivalent Day and Night Visibility

IR allows a significant reduction of bandwidth


Increase Situation Awareness Object Detection & Information Augmentation

Multiple objects are marked and tracked

Wind / RVR Overlay


Increase Safety: Video based Safety Net


Enhanced binocular with automatic tracking

Select object in panorama view get a close up in the binocular view

• verify landing gear up / down

• detect engine fire

• monitoring final approach

• monitor aircraft in control zone

AUA64

AFR003


Distance Measurement of Objects to compensate missing 3D view

report distance, speed and altitude of tracked object in real time


Provide an full integrated working position


How to increase efficiency ?

Apply a new working methode

Support controller with additional support tools

Increase Automation

Close integration of all systems

Introduce new planning tools for balancing workload

Multi airport handling is a key enabler!

Perspectives on Remote Tower Services

RemoteTower

Servicescommercial social


Perspectives on Remote Tower Services

RemoteTower

Servicescommercial social


Operational Aspects

Flexible opening hours to meet the requirements of the airport (or its customers respectively)

Flexible provision of ATC services during the operating hours of the airport

24/7 emergency operations feasible even outside normal opening hours

Trials proved operational reliability

Further improvements might and trials will be required for multiple airport scenarios

Improvements in service levels are possible


Commercial Aspects

High percentage of an airport’s costs are fixed

Not just capital costs for infrastructure but also operating costs, a significant proportion of which are driven either by regulatory requirements (safety and security), or by existing infrastructural requirements rather than traffic volumes

Nowadays, the cost of providing ATC services at an airport is fairly inelastic

Considering visiting costs at an airport the cost share of ATC is significant

Shared investment and operating costs should lead to reduced investments and reduced and more elastic operating costs

Remote towers allow significant cost savings and lower visiting costs


Safety Aspects

Timely implementation may be questioned by regulatory approval> Danger: Regulations and resulting concept of operation not harmonised and not

consolidated across EU Member States> EASA Rulemaking Task ‘Technical Requirements for Remote Tower Operations’

(RMT.0624)> Eurocae working group WG-100 ‘Remote and Virtual Towers’> Requirements of the resulting regulation need to be proportionate and cost-

efficient

Solutions need to be found for some tasks that are currently carried out by ATCOs or AFISOs> Meteorological observation> Runway inspections

Stored video and audio data may help accident and incident investigation

Chance to modernise ATC facilities with state-of-the-art technology


Conclusions

Remote tower services allow…

Improvements in service levels

Significant cost savings and lower visiting costs at airports and are a

Chance to modernise air traffic control facilities with state-of-the-art technology

Shifting focus

Initial focus was on low to medium density airports

Focus now also on contingency towers at medium to high density airports

Application of the technology for remote apron control?

Agenda

1. Why to remote2. Remote TWR as the solution3. Same concept, several features4. Expected benefits5. Conclusions

Why to remote…

! Need to comply with the enforced performance targets on cost‐efficiency as per EC Regulation 691/2010 on Performance Scheme

! Significant and fairly inelastic costs of ATC services provision in small/medium airports, including costs for installing or maintaining manned TWR several European regional airports have little chance of being commercially viable

! In certain EU regions, overcapacity of airport infrastructure relative to passenger current demand and airline needs

72

Need to reconsider the traditional way to provide ATS/ATC services!!!

73

The SESAR Concept of Remote Tower for Single Aerodrome (SDM‐0201) and its successor RT for Multiple Aerodromes (SDM‐0205) represent an extremely modular and flexible solution for sharing ATS services across

clusters of airports

… Remote Tower as the Solution!

74

A single Remote Tower Centre (RTC) serving several remote airports through a set of Remote Tower Modules (RTMs)

The RTC could be located at any location that has a very high level of integrity that meets all the service continuity requirements of the cluster of airports that are under its control

Remote Tower Concept does not require any special training, neither new methods, nor procedures, nor airspace redesign seamless solution to the users

Flexibility and adaptability of the solutions to several European operational scenarios

The Remote Tower concept is also suitable to provide service continuity at a major airport in a contingency situation (e.g. temporary unavailability of the local tower for refurbishing)

Same concept, several features

75

Cost EfficiencyStaff optimisationReduced costs of maintenance for local tower buildingMore efficient/centralised training, based on available RTMs

Access and Equity Possibility to maintain ATS services for airports otherwiseeconomically unsustainable.

Expected Benefits

Directly & Indirectly

76

• To foster the large scale deployment of the Remote Tower concept:

o Further investigations and demonstrations activities are required to prove the maturity and the feasibility of the concept

o Standardization and regulatory (i.e. licensing and service certifications) issues still need to be addressed, developed and then harmonized at European and at global level

But …

Conclusions

Remote Tower concept is among the most promising SESAR solutions, well responding to the business needs of several stakeholders, which can effectively contribute to the sustainable development of the transport system in Europe!!!
